It was nowhere near as bad as I thought, I managed to answer all the questions anyway! Except the simplex one, I was completely stumped even though my teacher went over it an hour before. Well anyway I counted up the marks I thought I'd got and it came to around a B? That's alright considering that my revision was less than thorough.

Did anyone else think the last question was scarily easy considering it was the last question on the paper? I'm convinced I missed something because it was so straightforward.
it wasnt all that straight forward? and i thought that in other past papers it has been similar.....

the hardest part in the last question were the C1, C2, and initial flow!

ALSO!... in the part of Gannts [however u spell it] graph, when asked about at 15 mins and 25 mins wat activities MUST be taking place, i think for 15 mins i put JUST C, and for 25 mins i put 3/4 activities down i think....

Nope, he's right. Only C HAD to be taking place on the 15th day.

Also, when everyone was calculating the C2 cut, did you remember to only add up verticies that went fromn the Source Set to the sink set? There was one arc that went from Sink set to Source set, so you shouldn't have added that one up.

on the last question was there two backflows and one forward flow? but i did get 98 for the flow. and this exam was alot more easier than the one set in january which i got a D in, so hopefully i went up a couple of grades.
